Becoming and maturing as a Christian is a process of knowing your self at an ever deeper level. Unfortunately (but really fortunately) this process only goes in one direction. The more you know, the more layers of the onion are peeled, the less pretty the picture becomes. The parts of you that are hidden are not the pretty parts. The process never ends, but one Sunday and thence forward, you say with awareness and sincerity:
“We are deeply sorry for these our transgressions. The burden of them is more than we can bear.”
Thanks be to God, Jesus Christ has paid the price for these our transgressions. We have been delivered from the domain of darkness and transferred to the Kingdom of His beloved Son.
